Description
Die Erfindung betrifft eine Brennkraftmaschine mit einem ersten Zylinder und einem zu diesem in Reihe angeordneten zweiten Zylinder, einer Kurbelwelle mit einem ersten, zwischen zwei ersten Hubwangen angeordneten Hubzapfen und einem zweiten, zwischen zwei zweiten Hubwangen angeordneten Hubzapfen, wenigstens einer Nockenwelle sowie einer ausgehend von der Kurbelwelle angetriebenen Massenausgleichseinrichtung.The invention relates to an internal combustion engine with a first cylinder and a second cylinder arranged in series therewith, a crankshaft with a first, between two first Hubwangen arranged crankpin and a second, arranged between two second Hubwangen crankpin, at least one camshaft and one starting from the Crankshaft driven mass balance device.
Aus der
Aufgabe der Erfindung ist es daher, eine eingangs genannte Brennkraftmaschine bereit zu stellen, die einen effektiven Massenausgleich bei gleichzeitiger Bauraumoptimierung ermöglicht.The object of the invention is therefore to provide an aforementioned engine, which allows effective mass balance while optimizing space.
Die Lösung der Aufgabe erfolgt mit einer Brennkraftmaschine mit den Merkmalen des Anspruchs 1, indem der kurbelwellenseitige Antrieb der Massenausgleichseinrichtung zwischen den ersten Hubwangen und den zweiten Hubwangen angeordnet ist. Damit wird, insbesondere in axialer Richtung, eine besonders kompakte Bauform erreicht. Aufgrund der zumindest annähernd symmetrischen Anordnung ergibt sich ein besonders effektiver Massenausgleich.The object is achieved with an internal combustion engine with the features of claim 1 by the crankshaft-side drive of the mass balancing device between the first Hubwangen and the second Hubwangen is arranged. This is achieved, especially in the axial direction, a particularly compact design. Due to the at least approximately symmetrical arrangement results in a particularly effective mass balance.
Besonders zu bevorzugende Ausführungen und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Particularly preferred embodiments and developments of the invention are the subject of the dependent claims.
Vorzugsweise sind der erste Hubzapfen und der zweite Hubzapfen bezüglich der Kurbelwellenachse um 90° zueinander versetzt, und die Massenausgleichseinrichtung umfasst eine erste Ausgleichswelle und eine zweite Ausgleichswelle. Mit zwei Ausgleichswellen ist gerade bei einer 90°-Kröpfung der Kurbelwelle ein besonders effektiver Massenausgleich gegeben, da bei einer derartigen Anordnung sowohl Massenkräfte 1. Ordnung als auch Massenkräfte 2. Ordnung auszugleichen sind.Preferably, the first crankpin and the second crankpin are offset with respect to the crankshaft axis by 90 ° to each other, and the mass balancer comprises a first balance shaft and a second balancer shaft. With two balancing shafts, especially with a 90 ° cranking of the crankshaft, a particularly effective balancing of mass is provided, since in such an arrangement both first-order mass forces and second-order inertia forces must be compensated.
Einer vorteilhaften Ausführung zufolge drehen die erste Ausgleichswelle und die zweite Ausgleichswelle gegensinnig zueinander. Einer anderen, ebenfalls als vorteilhaft angesehenen Ausführung zufolge, drehen die erste Ausgleichswelle und die zweite Ausgleichswelle gleichsinnig zueinander und beide entgegen der Kurbelwelle. Einem noch anderen Ausführungsbeispiel drehen die erste Ausgleichswelle und die zweite Ausgleichswelle gleichsinnig zueinander und beide in dieselbe Richtung wie die Kurbelwelle.According to an advantageous embodiment, the first balance shaft and the second balance shaft rotate in opposite directions to one another. According to another embodiment, which is likewise regarded as advantageous, the first balancing shaft and the second balancing shaft rotate in the same direction with respect to one another and both counter to the crankshaft. In yet another embodiment, the first balance shaft and the second balance shaft rotate in the same direction with each other and both in the same direction as the crankshaft.
Sehr zweckmäßig ist es, wenn der Antrieb der Massenausgleichseinrichtung ein kurbelwellenseitiges Antriebsrad, ein der wenigstens einen Nockenwellen zugeordnetes Antriebsrad, wenigstens ein der Massenausgleichseiririchtung zugeordnetes Antriebsrad sowie ein Zugmittel umfasst.It is very expedient if the drive of the mass balancing device comprises a crankshaft-side drive wheel, a drive wheel associated with the at least one camshaft, at least one drive wheel associated with the mass balancing control device, and a traction means.
Bevorzugterweise ist jeweils die dem Antrieb der Massenausgleichseinrichtung zugewandte Hubwange der ersten Hubwangen und der zweiten Hubwangen bezogen auf die anderen Hubwangen schmal ausgeführt.Preferably, in each case the drive of the mass balancing device facing Hubwangen the first lifting jaws and the second Hubwangen relative to the other Hubwangen narrow.
Die erfindungsgemäße Brennkraftmaschine ist in besonderem Maße als Range Extender zur Verlängerung der Reichweite eines elektrisch betreibbaren Fahrzeugs geeignet und bestimmt.The internal combustion engine according to the invention is particularly suitable and intended as a range extender for extending the range of an electrically operable vehicle.
Nachfolgend ist ein besonders zu bevorzugendes Ausführungsbeispiel der Erfindung unter Bezugnahme auf Figuren näher erläutert, dabei zeigen schematisch und beispielhaftBelow is a particularly preferred embodiment of the invention with reference to figures explained in more detail, showing schematically and by way of example
